Am I correct that block eruptors are only useful for SHA based mining? With Bitcoin valuation going up so far unless you have MegaHash hardware you can't really get a ROI.
Thanks!
Yes sha 256 only, but other coins use that as well, though they are not valueable enough to make up for the energy costs. But that can change ofc.
High Bitcoin value is a good thing for miners, because it means their mined fractual bitcoin is worth more. His stick does ~330MH/s and costs ~2,5 Watt in energy depending on the energy costs 330MH/s = less BTC than you need to pay for 2,5 Watt.
